O107400100004 AUTHOR (X.Peng, F.He, X.Long) O107400100005 INSTITUTE (3CPRSIU) O107400100006 REFERENCE (J,NIM/B,140,9,1998) O107400100007 (P,INDC(CPR)-44,20,1998) - prelim. publ. O107400100008 SAMPLE A natural titanium plate of 99.9% purity was rolled O107400100009 down to foil with thickness from 1 to 2 mg/cm**2. Each O107400100010 titanium foil was covered by both of aluminium foils O107400100011 with 1.2 and 1.5 mg/cm**2 thickness to prevent the lossO107400100012 of activity owing to atom recoil. The aluminium foils O107400100013 were a purity of 99.9%. Target thickness was determinedO107400100014 in all case by weight. The inhomogeneity of the O107400100015 titanium foil thickness was less than 3%. O107400100016 ADD-RES (COMP) The exciton model. O107400100017 DETECTOR (HPGE) O107400100018 FACILITY (CYCLO,3CPRSIU) The 1.2-m cyclotron. O107400100019 METHOD (STTA) O107400100020 (BCINT) O107400100021 (EXTB) The beam intensity was kept at about 300 O107400100022 nano-ampere. O107400100023 (ACTIV) Total charge amounted to 2700 micro-curie O107400100024 (GSPEC) About 15 hours after the stop of irradiation. O107400100025 ERR-ANALYS (ERR-T) The total error in the cross section data was O107400100026 determined by summing up in quadrature all the O107400100027 individual errors. The main sources of uncertainties: O107400100028 (ERR-1) The uncertainty of target inhomogeneity O107400100029 (ERR-2) The uncertainty of detector efficiency. O107400100030 (ERR-3) The uncertainty of beam current integrator. O107400100031 (ERR-S,0.8,3.8) The statistical errors of photopeak O107400100032 counting, which are from 0.8 to 3.8%. O107400100033 (EN-ERR) The uncertainty in the projectile energy O107400100034 contains two factors: O107400100035 1. The energy spread of the inherent beam, O107400100036 2. The energy loss inside those foils themselves.
